Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 154.12 g/mol gives Methyl 2-(furan-2-yl)-2-oxoacetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl 2-(furan-2-yl)-2-oxoacetate (CAS 33245-13-5), molecular formula C7H6O4 and molecular weight 154.12 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 2-(furan-2-yl)-2-oxoacetate (C7H6O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
